A Tiny Implant, A Huge Impact

iStent® is not only the world’s smallest medical implant known to be implanted in the human body — it also started a revolution in glaucoma treatment as the first Micro-Invasive Glaucoma Surgery (MIGS) device. The first MIGS device approved by the FDA, today iStent® has been implanted in over 300,000 eyes around the world, with more and more patients benefiting from the iStent® procedure every day.

An image of the Glaukos iStent device is enlarged to show the design including the self-trephinating tip, the retention arches and the snorkel where aqueous flows into Schlemm's canal. The iStent is made of medical grade titanium.

This tiny implant can also make a huge impact for patients who receive it. Once implanted in the eye, the device can help restore normal pressure in the eye. The iStent® is designed to:

• Restore your eye’s natural ability to drain the fluid that causes the increased pressure inside your eye
• Keep eye pressure at a normal level
• This may allow your doctor to reduce or eliminate your need for glaucoma medication
